1. Provide steps to reproduce the error
2. Explain what "does not work" mean. Is there an error message?
3. Follow the template for reporting bugs if you believe this is a bug. In your case more information about the system such as what browser you are using.

"Does not work for gmail.com" is nothing we can act on.

I have the same problem, but I have installed a CA root certificate and still cannot intercept HTTPS requests

mitmproxy --version
Mitmproxy: 8.0.0
Python: 3.8.6
OpenSSL: OpenSSL 1.1.1n 15 Mar 2022
Platform: Windows-10-10.0.19041-SP0

The client does not trust the proxy's certificate

What's the client? Some Python libraries don't use the Windows certificate store, that is not an issue with mitmproxy.

https://github.com/psf/requests/blob/main/docs/user/advanced.rst#ssl-cert-verification
psf/requests#5316
psf/requests#2966

In the future when reporting bugs follow the template. You didn't provide steps to reproduce the error and didn't specify what client you were using. But I could somewhat guess form the error in the window behind mitmproxy.

However, using Firefox browser on Windows, accessing HTTPS page will also be regarded as invalid certificate, which I can not find where the problem is

[Prinzhorn]

We have very extensive documentation at https://docs.mitmproxy.org/stable/, you might want to check it out. Firefox doesn't use the system store either.

If you have any suggestions how we can improve, feel free to open an issue.

After downloading mimproxy on my window 10 PC , then I typed the 'mitmproxy' command. It displays 502 Bad Gateway
